Re: 1911 Magazine Question
While, as many have said here, any 7 or 8 rnd magazine should work in any 1911 with a full-size grip frame, it is not always the case. 1911's can be very finnicy about magazines. The old GI spec guns were a little more forgiving, but some of the more modern, tighter fitted guns simply don't like some magazines.
I use McCormick Shooting Star mags presently. I have somewhere over 20K rounds through my Commander out of 6 of them. I don't recall ever having a magazine related failure with them. I've tried other mags, usually borrowed from buddies at the range with mixed results. For instance, a friend swears by Tripp Research mags, but they just won't run in my colt. On the other hand, the McCormicks I use and the Tripps he uses will run fine in his gun ( A Baer gun). I have tried Wilson mags and they run fine. Novak mags wouldn't run at all. I will say though that I can't remember one of my McCormics not running in whatever gun they were stuck in.
Regardless, I won't use a magazine for carry untill it has a couple hundred faiure free rounds through the gun I plan on using it with. I pretty much avoid cheap gun show magazines all-together.
